This manifold and up-pipe kit replaces the restrictive factory exhaust plumbing on 2011-2016 GM 6.6L Duramax LML with a larger inner diameter path from the head to the turbo.

Key Features

  • High-sil moly cast iron manifold
  • Internally sleeved up-pipe bellows in aircraft-grade 304 stainless steel
  • Increased inner diameter for higher flow
  • Built-in bosses, pre-drilled and tapped 1/8 inch NPT for an EGT probe
  • Designed to lower exhaust gas temperatures and speed turbo spool-up
  • 50-state emissions legal under CARB Executive Order D-701-36
  • Black Ceramic Coating finish

Ceramic Coating

The ceramic coating acts as a thermal barrier and does not absorb heat as quickly as raw metal, which reduces surface temperature and thermal cycling and helps keep exhaust gas temperatures down. It also protects against moisture, road salt, oil, fuel and other corrosive chemicals.

Fitment

2011-2016 GM 6.6L Duramax LML applications.

Note: LML applications require modification to the upper control arm bushing heat shield. Up-pipe configuration can vary by model, so confirm yours before installation.
